Who was murdered the night Lord Lucan disappeared?

The victim of the murder has never been a mystery.

Sandra Rivett, 29, was a bubbly redhead who’d been working as Lady Lucan’s nanny for just over two months.

Estranged from her husband Roger Rivett, Sandra was a one-time hairdresser who got her job with the Lucans through an agency. Although she had no nursing qualifications as such, Sandra was by all accounts a good-natured cheery worker who adored the children.
